I prefer to wait with this until the kernel patch gets approved and
pushed into wireless-testing.git.

Could you please explain what this is trying to do? It does not look
correct taking into account that I would assume similar control port
behavior to be used with KEY_MGMT_802_1X, KEY_MGMT_PSK,
KEY_MGMT_802_1X_SHA256, and KEY_MGMT_PSK_SHA256.
